DFSMS/VM DirMaint 1.5.0 Requirements

The following should be carefully reviewed and followed if DirMaint 1.5.0 (product number 5748-XE4) will be the CP directory manager when using DFSMS/VM minidisk management services.

• DFSMS APAR's VM59612 and VM62140 must be applied.
• Verify DirMaint's EXTENT CONTROL contains the following:
  1. The AUTOBLOCK section contains:

     
          3380  800 540 1 CKD
          3380  512 690 1 CKD

          3380 2048 270 1 CKD
          3380 4096 150 1 CKD
     

  2. The DEFAULTS section contains:

     
          3380 885
     

     or any number larger than 2 plus the number of DGTSRVnn ids.
  3. Make sure the REGIONS section does not contain an entry for volume $$$$$$, or if present, the device type is 3380.
  4. Make sure the EXCLUDE section contains entries for each minidisk management server virtual machine's (DGTSRVnn) 0500 and 05FF minidisks, for example:

     
          DGTSRV01 500
          DGTSRV01 5FF
     

  If any changes are made to the EXTENT CONTROL file, issue the DIRM RLDEXTN command.
• Verify DirMaint's CONFIGnn DATADVH contains the following:
  • UPDATE_IN_PLACE=YES

  If any changes are made to the CONFIGnn DATADVH file, issue the DIRM RLDDATA command.
